I was outside in the front yard at 11:30 pm on Friday night to do what I thought would be a few quick shots to test a new fisheye lens (7Artisans 7.5mm f/2.8 II). The first exposure showed a red glow on the northern horizon, so I ended up doing many iterations and eventually moved out onto the road to get a better perspective.
The red auroral glow reached up to about 8° above the horizon. That would put it overhead somewhere in Canada, over a 1000 mi to the north. The sky brightness was measured as 21.65 mpsas, somewhat brighter than previous nights, but still very dark. There seemed to be more green airglow this night, which contributed to the increased brightness.

The curved horizon is caused by the distortion of the fisheye lens. On the right, the northern Milky Way is rising over Snowshoe Mountain and gradually blending in to the pink auroral glow to the left side of the frame. There were also clouds floating around, some silhouetted against the aurora and Milky Way, and some lighter ones overhead.
A digital 3x3 median filter was also applied to these images to eliminate the distraction of the fainter stars:
